CHAFE-IRON FOR VEHICLES.

S1ECIFICATION forming part Of Letters Patent No. 653,217, dated July 10,1900.

Application filed October 17,1899. Renewed May 18, 1900. Serial No.17,172. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH H. CUTLER, a citizen of the United States,residing at West Medway, in the county of Norfolk and State ofMassachusetts, have invented certain new and useful Improvements inChafe-Irons for Vehicles, of which the following is a specification.

My invention relates to chafe-irons for vehicles, the object being toprovide a device of this character which will combine simplicity andeconomy of construction with effectiveness anddurability in use.

The invention comprises a supporting and attaching plate, anantifriction-roller, and novel means for supporting the roller inoperative relation to the attaching-plate.

The construction and novel features of the invention will be fullydescribed hereinafter and defined in the appended claim, in connectionwith the accompanying drawings, which form a part of this specification,and in which Figure 1 is a top plan view of a chafe-iron embodying theinvention. Fig. 2 is an end elevation of the same. Fig. 3 is a plan viewof the attaching-plate detached; and Fig. 4 illustrates the roller andits supporting and securing devices detached, but arranged with respectto their relation when assembled.

The reference-numeral 1 designates the attaching-plate, formed withopenings 2 to facilitate its attachment to the side of a vehicle-bodyand having parallel projecting ears 3 and 4-, which are bored to receivethe journals of the antifriction-roller 5. The ear 3 of the plate isformed with a bearing 6, the outer end 7 of which is of conical form tocorrespond to a conical journal 8, projecting from the adjacent end ofthe roller 5. The ear 4 of the plate is formed with a throughopening 9,the outer end 10 of which is internally screw-threaded to receive ascrewplug 11. The end of the roller 5 adjacent to the car a is providedwith a conical seat 12 to receive a pin 13, the inner end 14 of which isof conical form.

To support and secure the roller in position between the ears of theplate 1, I employ at one end of the roller a coil-spring 15, which restswithin the bearing 6, a concavo-convex disk 16, preferably made ofsteel, and a cupshaped leather washer 17'. As shown by the dotted linesin Fig. 1, the steel disk 16 bears against the spring and the cup 17bears against the disk and receives the'conical end of the journal 8. Atthe opposite end of the plate the roller is secured by the pin 13, whichis held in place by the screw-plug 11. Between the inner conical end ofthe bearing 12 and the end 14: of the pin 13 are arranged a coilspring18, a disk 19, of steel, and a cup-shaped leather washer 20, similar tothe parts 15, 16, and 17 at the opposite end of the roller.

The construction above described permits both the openings 6 and 12 tobe drilled bya single drill.

The roller is adapted to revolve freely and noiselessly, the yieldingwasher -cups and springs contributing to this result.

1 claim-- The combination with an attaching-plate formed with parallelears having alined openings; of a roller formed at one end with aconical journal, and at its opposite end with a conical bearing; acoil-spring, a disk and a washer between the conical journal and thewall of its bearing; a conical pin extending through one of the ears ofthe plate and projecting into the conical bearing of the roller; ascrew-plug for securing said pin; and a coil-spring, disk and cup-shapedwasher between the conical pin and the conical wall of theroller-opening.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH H. CUTLER. Witnesses:
